Description

The motor of fluid energy supply and pump

Reference to provisional application

The application is based on the U.S. Provisional Patent Application No.61/192 that is entitled as " Fluid Powered Motor andPump " that submitted on September 23rd, 2008, and 927 and require its preference, and after this it is carried out reference.The whole contents of this application is incorporated herein by reference.

Technical field

The present invention relates to the motor and the pump of fluid energy supply, and particularly, but needn't relate to the motor and the pump of liquid (or energy supply liquid) energy supply exclusively by for example water.Motor and pump especially can be used in combination with the filtration system of swimming pool and wabering place, though this motor and pump also can otherwise use.

Background technique

The U.S. Patent No. 4,449,265 that licenses to Hoy has been described a kind of example of wheeled automatic swimming pool cleaner device.For the wheel energy supply is the propulsion device that comprises propulsion device member and paired blade.The emptying propulsion device causes water and the blade in the swimming pool to interact, and rotates the propulsion device member.Propulsion device is reversible, and wherein propulsion device member obvious transverse movement when pool cleaner reaches the swimming pool edge is so that realize backward rotation.

The U.S. Patent No. 6,292,970 that licenses to people such as Rief has been described a kind of turbo-driven automatic swimming pool cleaner device.This cleaner comprises the turbine shroud that defines the mobile chamber of water, is positioned with rotor in the mobile chamber of water.Comprise that also a series of pivots are connected to the blade of rotor in the mobile chamber of water.Make rotor go up with the interactional water of blade and rotate, pivot when running into " large scale fragment ", make fragment, so that collect through housing at blade in a direction (shown in the Rief patent clockwise).The content whole of Hoy and Rief patent is incorporated herein by reference.

Summary of the invention

The present invention is directed to traditional propeller and turbine and provide effectively alternative.The present invention also can be presented as pump, and if desired, can be between motor and pumping function dynamic translation.Though the present invention can be used in combination with the others of the filtration system of swimming pool or wabering place, perhaps will become the part of any other system of rotational energy from for example transformation of energy of suction or pressure source as needs or hope, device of the present invention has special favourable part as being the motor of automatic swimming pool cleaner device energy supply.

The current preferred form of the present invention generally includes the main body with at least one inlet and at least one outlet.The location is one or more pairs of blades in the main body, and its distal side edge (if desired) can be a local compliance, passes through to help fragment.But this local compliance not necessarily.Paired lodicule of the present invention can Vertical location, rather than is placed in the same level (perhaps as one man being shaped).In other words, if blade itself is a general plane, and in pairs in the blade is positioned at first plane, and then another in the blade can be positioned at second plane perpendicular to first plane in pairs.In other form, though some the angle difference between the orientation of blade can be favourable in pairs, these paired blades do not need and must be perpendicular to one another.In other form, can be favourable though have differential seat angle between the orientation of a plurality of blades, blade does not need must be in pairs.

In having the of the present invention at least a form of paired blade, first pair of blade connects by axle.Blade is connected to base via hinge, bearing or other connected element in addition.In the form of (but not all) more of the present invention, base is constructed such that blade centers on the axis of aiming at at least a portion of axle and necessarily rotates, and base and connected element also are used for limiting the rotation of blade.Preferably, blade can be around the angle of these rotational 90 degree, though also can carry out the rotation of other angle.

At least this mode of execution also comprises second pair of blade, and it connects by axle equally and is connected to base.Advantageously, each of two axles can be non-linear, makes axle to intersect, and do not interfere and do not rotate with blade, again can be so that the part of each remains in the same level.In addition, two bases can be configured to be installed together, and form the overall structure of a plurality of at least parts of holding two axles.Arbitrary or two bases can comprise outward extending axle, this outward extending axle can: (1) provides during as motor in the present invention and rotates output, and (2) provide during as pump in the present invention and rotate input.

According to main body of the present invention can be (perhaps the having hollow space) of hollow, and blade and base can be installed in the hollow space.The overall structure that comprises blade and base can be rotated complete 360 deg (being the form of blade wheel) around outward extending axle (or a plurality of axle) as required clockwise or counterclockwise.Therefore, blade of the present invention can center on two different rotational in operation, though their preferably not linear motions, this is different from the propulsion device member of Hoy patent.

Main body also can be configured to provide flow restriction portion.This limitation part can cause blade to rotate when contacting with blade, makes its surface be parallel to (or being roughly parallel to) flow direction through main body.This rotation causes the blade rotation paired with described lodicule then, makes its Surface Vertical in flow direction.The result is that in a pair of blade provides Minimum Surface Area with respect to flow direction, and another provides maximum surface area with respect to flow direction, thereby suction force or pressure are with the efficient supply high torque (HT) output of maximum in rotating integrally-built process.

In other words, the present invention mainly uses the surface area difference to cause rotational motion.Two fluid flow pressure that blade ran into of a pair of blade are identical (perhaps roughly the same); Compare with another blade, a blade only flows with respect to fluid bigger surface area is provided.This design is different from the angle of rake design of standard significantly, and the angle of rake design of standard is that the jet fluid on propulsion device one side is poor at the side of blade build-up of pressure, therefore forms and rotates to solve unbalanced problem.

In addition, in the standard propulsion device, the blade relative with the blade of injected fluid impact be moving fluid on the direction opposite with flow direction.In this case, blade " is pulling fluid ", has reduced the whole efficiency of this device.By contrast, this significant " towing " phenomenon does not appear in the present invention.

Therefore optional not exclusive purpose of the present invention is to provide a kind of device of fluid energy supply, and this device can be as motor or pump (or simultaneously as motor and pump).

Another optional not exclusive purpose of the present invention is to provide mainly a kind of or uses the surface area difference to cause the device of the fluid energy supply of rotational motion uniquely.

Further optional not exclusive purpose of the present invention is to provide a kind of device that adopts the fluid energy supply of at least one pair of blade, blade of a pair of blade with this to another blade of blade not coplane, perhaps inconsistency ground orientation.

In addition, optional not exclusive purpose of the present invention is to provide a kind of blade that is configured to around a plurality of rotational.

Same optional not exclusive purpose of the present invention is to provide a kind of device with fluid energy supply of a pair of blade that connects via non-linear axle.

In addition optional not exclusive purpose of the present invention is to provide a kind of device that is particularly conducive to the fluid energy supply that is used in combination with the automatic swimming pool cleaner device or as the miscellaneous equipment of the filtration system part of swimming pool, wabering place or hot tub.

Embodiment

Shown in Fig. 1-2 is exemplary means 10.Device 10 can be used as motor or pump, perhaps is configured to the transformation of energy from suction or pressure source is become any other device of rotational motion.Device 10 can comprise main body 14 and the outward extending axle 26 that limits inlet 18 and outlet 22.Though in Fig. 1-2, described two so outward extending axles 26, also can adopt more or less axle 26.Equally, though be described as elongate rod at Fig. 1-2 axis 26, they can with shown in structure or be shaped differently.

If desired, main body 14 can comprise at least the first and second parts 30 and 34.If like this, first and second parts 30 preferably in use are connected shown in Fig. 1-2 with 34.At least a portion of main body 14 is (though not necessarily) joint and (2) and 26 an axis symmetry that overlap between (1) first and

second part

30 and 34 in addition preferably.The fluid that flows through main body 14 can be from entering the mouth 18 to outlet 22, perhaps from exporting 22 to inlet 18.Therefore, " inlet " of the main consuming body 14 and " outlet " for convenience here, and " inlet " is the outlet of main body 14 sometimes, and " outlet " at this moment can be the inlet of main body 14.

Shown in Fig. 1-2, that be positioned at main body 14 is exemplary blade, blade or blade 38 and limitation part 42 and wheel hub or

base

46A and 46B equally.Blade 38 can directly or indirectly be connected to outward extending axle 26 with one or more similar blades.When device 10 was used as motor, the fluid and each blade 38 that flow through main body 14 interacted, so that cause axle 26 to rotate.

Fig. 3-5 has described a plurality of blades 38.It can be paired that Fig. 5 has described blade 38 (if desired) especially; Two so paired blades are represented in the accompanying drawings, wherein a pair of blade 38A, the 38B of comprising, and another is to comprising blade 38C, 38D.In the current preferred form of device 10, blade 38A is connected by axle 50A with 38B, and blade 38C is connected by axle 50B with 38D.Preferably, between

blade

38A and 38B, directly do not connect on the one hand, and between

blade

38C and 38D, directly do not connect on the other hand yet.Alternatively, axle 50A and 50B are configured to intersect with the form that the rotation of

blade

38A and 38B is interfered with the rotation interference and the axle 50B that avoid a 50A and blade 38C and 38D.Preferably include four blades 38 (for

example blade

38A, 38B, 38C and 38D) though install 10, can adopt more or less blade 38.

In the form of the lodicule shown in Fig. 3-5 38, axle 50A is similar to slender cylinder, and therefore can limit roughly longitudinal axis X.Axle 50B limits roughly longitudinal axis Y similarly.But the axle 50A middle body 54A off-axis X, basically from the axis X lateral shift so that form nested space 58A.Equally, the middle body 54B of axle 50B is from axis Y translation, so that form nested space 58B.Therefore axle 50A can roughly be placed in the plane identical with axle 50B, and wherein nested space 58A and 58B are adjacent.In form shown in Figure 5, because nested space 58A and 58B aim at, middle body 54A is at the top of middle body 54B, and is not in contact with it.

Fig. 5 is the preferred relative orientation of a pair of lodicule 38 of expression in addition.Lodicule 38A for example is illustrated as having the main surface 62 (and apparent surface's (not shown)) in page plane usually in Fig. 5.By contrast, lodicule 38B is illustrated as having main surface and the apparent surface 66 (and unshowned apparent surface) who is approximately perpendicular to page plane.In other words, the plane of containing main surface 62 and process axis X is preferably perpendicular to the plane of containing main surface 66 and process axis X, makes main surface 62 and 66 be offset 90 degree.Therefore, when main surface 62 provides maximum surface area with respect to the flow direction through main body 14, main surface 66 will provide Minimum Surface Area with respect to flow direction.The relative orientation of

lodicule

38C and 38D is preferably similar; The main surface 70 that contains lodicule 38D also can be perpendicular to the plane of the main surface 74 that contains lodicule 38C and apparent surface 78 and process axis Y through the plane of axis Y.

Though the apparent surface of lodicule 38 preferably is offset 90 degree in pairs, this orientation of angle accurately not necessarily.For a pair of lodicule 38, angular deflection should be greater than 0; Therefore the present invention considers any other this angular deflection.But, need produce gratifying result in many cases greater than for example angular deflection of 5,20 or 45 degree.Because axle 50A and 50B and surface 62,66,70,74 and 78 (etc.) preferred form be rigidity,

lodicule

38A and 38B keep its angular deflection always,

lodicule

38C and 38D keep its angular deflection equally always simultaneously.But if desired, lodicule edge (for example edge 82 of lodicule 38A) can be flexible, to help fragment through main body 14, perhaps reduces the frictional loss of lodicule 38 (or main body 14).

Axle 50A and 50B and the wheel 86 that contains bearing can be placed in the base 46B as shown in Figure 3.Base 46A (Fig. 4) can be installed in the top of wheel 86, and is attached to base 46B.Resulting structures feasible axle 50A and 50B and the lodicule 38A-D that links rotate around the axis Z that overlaps with axle 26.When device 10 is used as motor,, form rotation around axis Z because fluid flows through main body 14; If fluid 18 enters via inlet, rotation will be on the direction of arrow A (see figure 3).On the contrary, if fluid enters via outlet 22, rotation will be carried out in the opposite direction, as shown by arrow B.(alternatively, it is interior so that make rotation direction reversed that limitation part 42 can suitably be positioned at main body 14 again, is to enter via inlet 18 or outlet 22 and do not change fluid).Because axle 26 is connected on the rotatable parts, they also will rotate, and provide to carry out the required energy of useful work.

In use, lodicule 38 is also around another rotational.Lodicule 38A-B for example can rotate around axis X, and lodicule 38C-D can rotate around axis Y simultaneously.The rotation of this second type causes by limitation part 42.

For example, suppose that lodicule 38A-D constructs as shown in Figure 3 and orientation, and on the direction of arrow A, rotate.Lodicule 38C is normally vertical when the limitation part 42 of its approaching expression form in the slope in this example.Further motion on the direction of arrow A causes the surface 78 contact limitation part 42 of lodicule 38C, the inclined surface 90 of limitation part 42 (seeing Fig. 2 equally) forces lodicule 38C to rotate around axis Y, so that essentially horizontally redirect (its surface 74 is finally towards last, as the surface 62 of Fig. 3).Along with lodicule 38C turns to the approximate horizontal position from vertical position roughly, paired lodicule 38D will turn to roughly vertical position from the approximate horizontal position.In fact, this pass ties up among Fig. 3 represents by paired

lodicule

38A and 38B: lodicule 38A is urged to the approximate horizontal orientation by limitation part 42, and it is roughly vertically-oriented to cause paired lodicule 38B to take.

According to Fig. 3, continue to describe this example, the fluid that enters inlet 18 can advance to outlet 22 via the either side of base 46B, promptly passes through passage 94 and passage 98.(but preferably, passage 98 is subjected to bigger basically restriction than passage 94, makes to have only limited fluid process).The fluid that enters inlet 18 runs into lodicule 38D at first.Because lodicule 38D is an approximate horizontal, it is with respect to providing Minimum Surface Area from 18 directions that flow to the fluid of outlet 22 that enter the mouth.This result also is like this for the lodicule 38A (and in fact sealing or roughly sealed passage 98) that is forced into horizontal position by limitation part 42.By contrast, lodicule 38B is roughly vertical, provides maximum surface area (form on surface 66, this surface is not shown in Fig. 3, but represents) with respect to fluid flow direction in Fig. 5.This different surface area causes mobile fluid to promote lodicule 38B, thereby lodicule rotates on the direction of arrow A.

Though not shown in Fig. 3, limitation part 42 can continue perhaps have the inclined surface near inlet 18 in addition through passage 98, makes device 10 oppositely to operate.In addition, if supplying energy is to rotate one or more axles 26, axle 26 can make device 10 can be used as fluid pump so that lodicule 38 rotates around axis Z then, it by fluid " energy supply ", and does not consider how to make axle 26 to rotate in operating process in this case.Therefore, device 10 is provided for using streaming flow to cause the multifarious efficient mechanism of rotation.

Provide above content in order to illustrate, to explain and describing embodiments of the present invention.Those of ordinary skill in the art will understand at the modification of these mode of executions and remodeling, and not depart from scope of the present invention or spirit.
